Figure 1.
Case studies of pseudogenized genes in pangolins. (A) Three tooth development-related genes were pseudogenized and may be related to the lack of teeth in pangolins. There was a frameshift deletion in positions c1311–c1324, a single base pair deletion in c1476, and an insertion of AGAT at position c1621, resulting in another premature stop codon in the AMBN gene. The AMELX gene contains a large deletion at position c438–c497. (B) Two genes were pseudogenized and may be related to the poor vision of pangolins. Blue = insertion, green = deletion, pink = stop codon.
